From 1220aba99bc78290bb89ade649719508e3031e4b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 10 Nov 2009 14:11:46 -0800 Subject: i965: Fix VS constant buffer value loading. Previously, we'd load linearly from ParameterValues[0] for the constants, though ParameterValues[1] may not equal ParameterValues[0] + 4. Additionally, the STATE_VAL type paramters didn't get updated. Fixes piglit vp-constant-array-huge.vpfp and ET:QW object locations.
